Influence of occlusal contact of superstructure on mandibular deviation with increasement of occlusal force.

种植体在牙齿缺失修补中的应用越来越多。人们认为，由于种植牙与天然牙相比缺乏牙周韧带组织，所以在咬合时种植牙的运动与天然牙不同。然而，对于咬合与上层建筑的接触，目前还没有科学研究的标准。在本研究中，我们旨在研究咬合接触对牙尖间位置咬合稳定性的上层结构的影响。检查现有的咬合检查方法是否能够用于种植体的评估，因为有必要客观地捕捉长系列的咬合接触和种植体的变化。此外，为了评估观察种植体治疗患者长期通道时骨整合状态的变化，开发了IM检查器。因此，在咬合接触评估中显示了添加图像法和T-Scan II的实用性，在种植体可移动性评估中显示了IM检查器的实用性。用咬合评估设备显示种植体患者的咬合接触状态，咬合强度提高时咬合接触趋于稳定，与健康志愿者的咬合接触趋势相同。研究了模型实验中以种植体直径和种植体深度为种植体迁移率指标的IM值对IM值的影响。将水平方向和垂直方向分别激发到种植体上，并对测量结果进行评估。我们建议IM检查器能够测量种植体的移动性，并且这种移动性能够评估骨整合水平。

The application of the dental implant to the tooth loss mending increases in the daily clinic now. It is thought that movement of dental implant different from natural teeth is done at the clenching because the periodontal ligament organization is lacked in the dental implant compared with natural teeth. However, it is a current state that there is no standard based on scientific research as for the occlusal contact to the superstructure.In this research, we aimed to examine the influence of the occlusal contact on the superstructure exerted on the stability of the occlusion in the intercuspal position. It was examined whether existing occlusal examination methods were able to use for the evaluation of the implant because there was a necessity for objectively catching a long series of occlusal contact and implant's changes for that. Moreover, to evaluate the change in the state of osseointegration when long-term passage in the patient treated with implant was observed, the IM checker was developed.As a result, the utility of the add-picture method and T-Scan II was shown in occlusal contact's evaluation and the utility of the IM checker was shown in the implant mobility evaluation. Implant patient's state of the occlusal contact was shown with occlusal evaluation equipment, and the occlusal contact when clenching strength was raised stabilized, and showed the tendency same as a healthy volunteers. The influence on the IM value whose diameter and depth of the implant body are the implant mobility indices in the model experiment was examined about the IM checker. Horizontal direction and the vertical direction were excited to the implant body and the measurement was evaluated. It was suggested the IM checker was able to measure implant's mobility, and this mobility to be able to evaluate the level of osseointegration.
